Linux pthread线程同步相关的API学习

原因

最近在深入理解Dalvik虚拟机的内部线程控制体系，其中涉及大量pthread的相关操作，现在统一浏览一下。

?

#include
gcc -lpthread xxx.c -o xxx.out

主要API:

标识
int pthread_equal(pthread_t tid1, pthread_t tid2);//若相等则返回非0值,否则返回0pthread_t pthread_self(void);创建int pthread_create(pthread_t *restrict tidp, const pthread_attr_t *restrict attr, void*(*start_rtn)(void*), void* restrict arg);//success return 0, else return errno终止void pthread_exit(void *return_value_ptr);int pthread_join(pthread_t the_exit_pthread_, void ** return_value_ptr_ptr);int pthread_cancel(pthread_t tid);void pthread_cleanup_push(void (*rtn)(void*), void* arg);void pthread_cleanup_pop(int execute);int pthread_detach(pthread_t tid);同步互斥量int pthread_mutex_init(pthread_mutex_t*restrict mutex, const pthread_mutexattr_t * restrict attr);int pthread_mutex_destroy(phtread_mutex_t *mutex);//success if return 0, else return errnoint pthread_mutex_lock(pthread_mutex_t * mutex);int pthread_mutex_trylock(pthread_mutex_t * mutex);//异步int pthread_mutex_unlock(pthread_mutex_t * mutex);同步信号量
